Because there are several periods of tectonic movement and several tectonic zones " development and complex superposition at da gangshan hydropower staion , geological structure in dam area is great complex and water - bearing media has the characteristic if inhomogeneity , which make it difficult to further clarify the burial condition of different bearing aqueous structure and the development of ground water system at the dam area 由于大岗山水电站坝区存在多期次的构造运动以及多个构造带的共同发育、复合叠加，使得坝区地质构造显得错综复杂以及含水介质的不均一性，使得进一步阐明坝区不同承压储水构造埋藏条件和坝区地下水系的发育特点变得很困难。
This paper deals with the water - bearing media and water - bearing quality of the rocks in the damsite , at first , then it concludes two water - bearing space structures , namely , t - shaped and y - shaped structures , after the classification of the different rocks ' water permeability . furthermore . on the basis of the dynamic state of the ground - water and the hydrogeological conditions of this area , the groun - water system of the area has been prelimilarily divided accordingly 本文首先研究了坝址区出露岩体的含水介质和含水性，并对岩体透水性进行了分类，总结出了两种岩体的含水空间结构，即“ t ”字型与“ y ”字型结构。在此基础上通过研究地下水的动态，以及水文地质条件对本区的地下水系初步进行了划分。
